Ms. Ronson’s newest collection was a riff on a ’70s-era heroine who reclaims her independence. Sweeping skirts, embroidered dresses and flowing trousers were free of constricting elements. With the exception of a floor-grazing lace skirt styled for the runway without a lining, very little skin was on display. Instead of jewelry, models in understated makeup wore turbans and scarves over long, loose curls.

Detailing was draw-you-in-close subtle: knotted fabric held delicate chains that draped over shoulders, and skirts and blouses featured jewelry-like metal-tinged tassels and small metal-finished buttons.

“It’s very covered but still sexy, with baroque ’70s touches,” Ms. Ronson said.

Ms. Ronson’s sister, DJ Samantha Ronson, flew in from Los Angeles to provide the music before and during the show. The two siblings discussed the set list around an hour before showtime, leading to a playlist that included the Eagle’s “Life in the Fast Lane,” Tom Petty’s “You Don’t Know How It Feels,” Ted Nugent’s “Stranglehold” and Heart’s “He’s A Magic Man.” As in most Charlotte Ronson affairs, either her sister Samantha or brother Mark try to be on hand to lend their talents.

“It’s just what we do, we’re family,” Samantha said. “We’re all good at what we do. Why would she want anyone else involved when she could just have her family? No one else is going to care about you as much as your family does.”
